A seldom collected parasitoid of the pine aphids, Praon bicolor Mackauer, 1959, was captured in Malaise traps, mounted near the pine forests of Alborz Province (north central of Iran). It is the first record of this species from Iran and from the central Asian area. A brief diagnosis according to the morphological characters is presented and the host range within the conifers aphid parasitoids is also discussed.

A faunistic survey was conducted in Ardabil province (North-western Iran), during spring 2013 to study the ichneumonids (Hymenoptera: Ichneumonidae) associated with grasslands in this area. Samplings were carried out by the sweeping net in natural grasslands, neighboring fields and orchards. A total of twelve ichneumonid species belonging to nine genera and five subfamilies were collected and identified. The species were identified as follow: Collyria coxator (Villers, 1789), Diadromus collaris (Gravenhorst, 1829), Diplazon laetatorius (Fabricius, 1781), Diplazon pectoratorius (Gravenhorst, 1829), Homotropus crassicornis (Thomson, 1890), Homotropus elegans (Gravenhorst, 1829), Homotropus signatus (Gravenhorst, 1829), Lysibia nana (Gravenhorst, 1829), Orthocentrus castellanus (Ceballos, 1963), Picrostigeus setiger (Brischke, 1871), Promethes sulcator (Gravenhorst, 1829) and Syrphophilus bizonarius (Gravenhorst, 1829). Homotropus crassicornis is newly recorded for the fauna of Iran. An identification key to the known species of the genus Homotropus Foerster, 1869 from Iran is presented.

A checklist of Iranian Cryptinae (Hymenoptera: Ichneumonidae) for all species recorded of Iran is given. The list is based on detailed studies of all available published data and some new collected samples. Until now 123 species in 42 genera belonging to 3 tribes of this subfamily have been known from Iran. Cryptinae is the most species-rich subfamilies of Ichneumonidae, and has a worldwide distribution. Two genera, Goryphus Holmgren, 1868 and Thaumatogelis Schwarz, 1995 were recorded for the first time for the Iranian fauna. Many parts of the country are still studied insufficiently or even not studied at all, so we suppose that the total species richness in Iran is essentially higher.

The Ichneumonidae fauna of Kerman province, Iran, was surveyed in April 2013 to June 2014. In total, 35 species belonging to 22 genera and eight subfamilies were collected and identified, of which Cryptus armator Fabricius, 1804; Enizemum schwarzi Diller, 1987 and Barichneumon gaullei Berthoumieu, 1903 are new records for thefauna of Iran. An updated list of Ichneumonid species for Kerman province is presented. These data can be useful for biological control programs.

A total of 12 species belonging to 10 genera of these two subfamilies were collected and identified. They were Cryptus inculcator (Linnaeus, 1758); Dichrogaster longicaudata (Thomson, 1884); Dichrogaster saharator (Aubert, 1964) and Mesostenus albinotatus Gravenhorst, 1829 (subfamily Cryptinae); Anisobas cingulatellus Horstmann, 1997; Apaeleticus bellicosus Wesmeal, 1845; Barichneumon derogator (Wesmeal, 1845); Ctenichneumon devylderi (Holmgren, 1871); Ctenichneumon edictorius (Linnaeus, 1758); Diadromus collaris (Gravenhorst, 1829); Heterischnus filiformis (Gravenhorst, 1829) and Lysibia nana (Gravenhorst, 1829) (subfamily Ichneumoninae) of which the genus Apaeleticus Wesmael and three species including M. albinotatus, A. bellicosus and B. derogator are new records for the fauna of Iran. All species are new for the fauna of Kerman province.

A survey was performed to investigate the fauna of Ichneumonidae in Fars province during 2012 to 2013. Totally, 14 species belonging to 13 genera and six subfamilies were collected and identified including: Exetastes adpressorius (Thunberg, 1822) (Banchinae); Diadegma semiclausum (Hellén, 1949) (Campopleginae); Cryptus inculcator (Linnaeus, 1758); Dichrogaster saharator (Aubert, 1964) (Cryptinae); Diplazon laetatorius (Fabricius, 1781); Enizemum ornatum (Gravenhorst, 1829); Homotropus nigritarsus (Gravenhorst, 1829); Homotropus signatus (Gravenhorst, 1829) (Diplazontinae); Colpognathus celerator (Gravenhorst, 1807); Diadromus collaris (Gravenhorst, 1829); Ichneumon sarcitorius Linnaeus, 1758; Virgichneumon callicerus (Gravenhorst, 1820) (Ichneumoninae); Orthocentrus asper (Gravenhorst, 1829); Picrostigeus setiger (Brischke, 1871) (Orthocentrinae), of which Exetastes adpressorius and Picrostigeus setiger are newly recorded for the fauna of Iran.

An updated checklist of the scorpiofauna of Iran is presented. The checklist is based on records of scorpion species which their presence have been confirmed in Iran through field expeditions, examination of scorpion collections, literature review, and personal communications with researchers. According to the presented checklist the scorpion fauna of Iran consists of 68 valid species (41 endemic to Iran) belonging to 19 genera and four families and 6 doubtful reports (belong family Buthidae). Hemiscorpius gaillardi (Vachon, 1974) and Compsobuthus jakesi Kovařík, 2003 reported for the first time from Hormozgan province. Odontobuthus tavighiae Navidpour et al., 2013 collected for the first time from Fars province. Kraepelinia palpator (Birula, 1903) and O. tirgari Mirshamsi et al., 2013 were new record for South Khorasan province fauna. The list is dominated by members of the family Buthidae (58 species) with 85.3% of total species. The level of regional endemism exceeds 60.3%. A dichotomic identification key to the Iranian species on the basis of a DELTA database has been provided.

The occurrence of Pauesia silana Tremblay, as an aphid parasitoid (Hym., Braconidae, Aphidiinae) in Tunisia is documented. The parasitoid was found in association with the Aleppo pine aphid, Cinara palaestinensis Hille Ris Lambers, infesting Pinus halepensis. Specimens were collected by the rearing of the mummified aphids from the colonies infested the pine trees in the Arboretum of the Institut Supérieur Agronomique Chott Mériem (ISA CM - Tunisia) during March–April 2021. A brief diagnosis is provided for the recorded parasitoid. This is the first record of a Pauesia species in Tunisia (out of the purposeful introduction of Pauesia antennata Mukerji). Two secondary parasitoids including Asaphes vulgaris Walker and Pachyneuron aphidis (Bouché) (Hym., Chalcidoidea, Pteromalidae) have also emerged from the mummified aphids. The known Cinara aphids and their associated parasitoids in the North African country are reviewed. Both Aleppo pine aphid and the newly detected parasitoid might be considered exotic species in North Africa, sourced from a recent accidental introduction inside the Mediterranean area, or a horizontal expansion across the North African countries.

Species of four chrysidoid families, Bethylidae, Dryinidae, Embolemidae, and Sclerogibbidae that occurred in Iran are reviewed. A total of 54 species within 27 genera from Iran are listed. The family Bethylidae with 34 species belonging to 16 genera was the largest group followed by Dryinidae with 17 species belonging to eight genera. The known Bethylidae species from Iran certainly represent a very small piece of the world fauna, distributed mainly in the Palaearctic region. Of the seventeen species of Dryinidae, the known distribution of ten species is known yet limited to the Palaearctic region, but five species are distributed in the north of the Afrotropical region (Arabian peninsula). The families, Embolemidae and Sclerogibbidae each represented by two and a single species in Iran, respectively. Embolemus huberi Olmi is here recorded from Kirghizstan, Turkey and Turkmenistan for the first time. Until now, no species of the families Plumariidae and Scolebythidae have been recorded from Iran. Despite the importance and diversity of both bethylids and dryinids, it seems that the least attempts have been done to study their fauna in Iran.
